TIRE FOR VEI-EICLE-WHEELS.

Specification of Letters Patent.

Patented March 10, 1908.

Application filed April 22, law. Serial no. 369,6 i8.

To all whom it may concern.

Be it known that I, THOMAS ALFRED SIL- vnnwoon, a subject of the King of England, residing at Nicholas Lane, Lombard street, in the city of London, En land, have invented certain new and useffi Improvements in and Relating to Tires for Vehicle- Wheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

Thisinvention consists of improvements in tires for vehicle wheels and is designed to prevent side slip or skidding. 4

According to this invention, the tire is formed of metal, preferably of steel, helically wound, the divisions being filled in by fiber or other suitable material or compound, left toharden, thus. softening the tread of the wheel, and; gripping the surface of the road to I obviate the side slip of the wheel. A'retainin ring is fixed by bolts or otherwise toeach In such retaining ring I fix a projectionwhich shall take. into a slot formed in'the tire so as to prevent creeping.

' and filled in the spaces left in the ribbon steel Instead of having the ribbon steel helically wound as aforesaid I may, in some cases, find itadvantageous to have fiat rings of steel,

with the compound placed between them,

'And in order that my said invention may be better understood'I will proceed to describe the same with reference to the drawing accompanying this specification, in Which:-.

Figure 1 shows an elevation of a wheel pro vided with my improved tire Fig. 2 shows ribbon steel formed into a helix; Fig. 3 shows a section through the rim of the tire.

The same letters of reference are employed to denote the same parts in all the views fa, shows a ribbon of steel set on. itsedge and formed into a helix as shown in section, Fig. 3, and detached at Fig 2. I

b shows a ribbon-like fibrous or other suitable. material or compound also set on edge helix for the purpose of softening the tread and deadening the noise.

0 shows two rings forming with the rim of the vehicle a box to receive the ribbon c and fibrous materials I), and one of which may be formed with the rim of the wheel and the other one may be suitably fixed thereon by bolts or otherwise.

' material inthe form of a helix of rib d shows a stud or projection fixedto one of the rings 0 and taking into a slot in the tire as shown. in section at Fig. 3 to prevent any lia-v bility of creeping of the tire.

In fitting wheels provided with this tire to vehicles I prefer to so fit them that the wheels on one side have a right-handed screw action and the wheels on the other side a left-handed action so that upon the vehicle tending to skid or sidesli such skidding or sideslip will be prevented y the combined action of the Wheels, or on each side of the car I may have one wheel with a left-handed helix and one with a right-handed helix iii certain cases.

In some cases I may find it desirable to rougher). or serrate the sides of the ribbon stee is formed in order to afford a grip for the filling material filled in between the coils of the metal.

' hat I claim and desire to secure by Letters Patent of the United States of America 1s:-

or the like from which the helix or ring.

1. A tire for vehicle wheels com osed of I ter-ial set on edge and a filling material between the layers of. ribbon material, substantially as and for the purposes set forth.

2. A tire for vehicle wheels provided with a helix of ribbon steel set on edge, in combina tion with a fibrous material separating the coils of said helix, substantially as and for the purposes set forth.

3. In vehicle wheels the combination of the rim )rovided. with plates forming 'a box, a material in the form of a helix of ribbon material set on edge, fixed in said box, and a fibrous material also having a ribbon form set on edge in said box between contiguous portions of the said ribbon material, substantially as described. I

l. in a vehicle wheel, the combinationof a box on the rim thereof, a spiral ribbon seton edge in said box, a fibrous material between THOMAS ALFRED SILVERWOOD,
